For future single-input 3D sources where the server supplies a separate 3D stereo

sync to the projector’s GPIO port instead, set Input GPI according to which

input# is used (i.e., according to your GPIO cable wiring).

DEFINE L/R DOMINANCE: Choose the leading frame, left or right. Correct order

depends on the cameras used during filming, and is needed to ensure smooth

motions. An incorrect setting creates motion artifacts.

5. DEFINE SYNC DISPLAY LOCATION:

 Set L/R Display Reference to Not Used.

 Set Display GPI to None.

DEFINE SYNC OUTPUT: Use L/R Output Polarity to set whether the 3D sync

signal output from the projector’s GPIO port (to your emitter or polarizer)

matches the L/R order of the incoming frames, or whether it is to be inverted—

i.e., reversed (R/L). Then set the Output GPO according to which of the

projector’s GPIO outputs is currently wired to your emitter or polarizer.

CONNECT GPIO (OUTPUT): From the projector’s GPIO port, connect your 3D

Stereo Sync cable to your 3D controlling device such as an emitter or polarizer.

NOTE: RealD 3D sync cable recommended.

ADJUST DISPLAY, SCREEN, ETC.: As desired, adjust the image color, etc.

Using the 3D Test Pattern

Use the 3D internal test pattern

to confirm 3D mode, L/R

orientation, and GPO settings.

This pattern automatically

activates 3D mode and

increases frame rate by a factor

of 6:2.

NOTE: The test pattern will

flicker significantly due to its

low frame rate, and is not

recommended for synchronizing

projector processing with your

3D device.

Image breakup

Increasing the Dark Time beyond its maximum may cause image break-up.

No 3D effect

Certain settings in the Custom: 3D Control menu are likely reversed.

Ghosting / Cross-talk

Ghosting or cross talk indicates that the eyes are detecting portions of the opposing

frame due to an “out-of-sync” system. Adjust Dark Time and/or Output Delay so that

the projector’s display output is synchronized with the gating (switching) of your

glasses.
